INSTALLATION in 4 steps
Pre-Installation
Before starting with mounting and removing cover off your car,
check to make sure that the vehicle is safely parked and that ALL
electrical components are switched OFF. Clean the bumper
thoroughly and dry it with clean clothes. Ask a fried or a family
member to assist you. This will make the installation much easier.
READ THE INSTRUCTION FIRST, BEFORE INSTALLING THE
SYSTEM, prepare the following listed equipment:
Drill & Drill bits, Measuring tape, Pencil & Marker, Plier & Screw
driver, Electrical tape, Multimeter voltage tester, Steel wire,
Sandpaper.
1. Mark the position of the sensors
Measure and mark the vertical position (center line) according to
diagram 1. Ensure that the position is above 50cm (ideally 55cm)
from the ground surface. NOTE: It must be directly vertical.
Diagram 1

Diagram 2 & 3
Measure and mark the horizontal position according to diagram 2.
The outer most left and most right sensor should ideally be 15m–
20cm away from the edge of the bumper. Locate the Center Line
and mark the position of the remaining sensors and according to or
to the near approximation of diagram 3.
NOTE: Try to locate a flat surface for the mounting of the sensors.
Once it is completed it should appear similar to diagram 1.
Diagram 2
Diagram 3
Rear Sensors A, B, C, D
should be mounted from
left to right with A being the
leftist side and D being the
rightist side.

2. Preparing to drill
First always check areas behind the bumper to see if it is clear to
drill. Attach the small drill bit and push lightly to make a small dent
in the bumper in the premarked area and drill all the way through
the bumper. This prework will make it easier afterwards to drill the
hole in the bumper without slipping while drilling to prevent
scratches to the bumper.
 Now attach the custom high performance drill bit supplied in
Package Contents. During the drilling process, hold the drill in a
steady-fixed-parallel ground position, like shown below:
 Lighty sand the newly drilled hole in your bumper with
sandpaper to get a smooth finish around the edge.
 Repeat this steps for the following 3 sensor holes.
3. Mounting the 4 sensors
Insert the sensors cable into its hole, until the sensor is touching
the bumper. NOTE: Ensure that the arrow mark (up) behind the
sensor points upwards. Push the edge of the sensor into the hole.
Do NOT push the centre area of the sensor!
The final position of the sensor in the hole should be as shown
here:

 Mark the sensor plug of each sensor or the end of the cable
with the letters A, B, C, D so it is easier to attach them in the right
order to the Control Box.
 Using a steel wire, tied the sensors cables to one end and
guide the other end through into the opening at the underside of the
vehicle until you can see it protrude inside the trunk compartment.
Gently pull on the protruding end until the cables are inside.
NOTE: Take care and gently pull the cables into the inside of the
trunk compartment. Do NOT use force! Avoid placing underneath
sensor cables near high heat source area such as muffler, exhaust
etc.
4. Wiring
Turn on the ignition so the car is under power (differs by the
model and the age of your car). DO NOT start the engine.
 Make your handbrake on. Then shift the gear to reverse.
 Remove the rear light. Using the electrical tester/multi-meter
to locate the correct power wire for the Reverse Light power line
(this will be the cable of the white reverse light). Mark the correct
wire with positive and negative.
NOTE: You need to find the reverse light power line!
 Shift the gear back to “Parking” for automatic and remove
the vehicle’s key. Car holders with gearshift just remove the
vehicle’s key.

Wire Connection
Follow the connection diagram of the control box.

Sensor A
Attach the black cable of the power cable to the car’s ground
(negative) or the negative of the reverse light.
 Attach the red cable of the power cable to the positive cable of
the reverse light. If necessary remove the wire isolation before
connecting.
 To attach the power cable to the positive and negative
cables of your car we suggest cable connector for each wire. After
connecting, wrap connection with electrical tape to prevent a short-
circuit.
NOTE: Check for correct wire before cutting and wiring.
Control Box Connection
Plug the power cable into the Control Box slot which is red.
 Plug the display cable into Control Box slot which is blue.
After testing the sensors, place and fix steadily the Control Box in
your car’s trunk, depending where you connect the power cable to
the reverse light.
NOTE: Power cable, sensor cables and display cable must be laid
to the position of the Control Box.

Sensor testing
Turn on the ignition so the car is under power (differs by the
model and the age of your car). DO NOT start the engine.
 Make your handbrake on. Then shift the gear to reverse.
 Place the display for testing in the trunk.
 ONLY plug in sensor A cable into the Control Box slot A.
Stand in ~2m distance from sensor A (the sensor should NOT
beep and the display should show two minus signs “– –“ in RED).
Then move slowly towards your car. In ~1.5m distance from your
car, the beeping sound starts and the display should show the
corresponding distance as you move closer and closer. You can do
it by yourself, but it is easier to ask a friend or family member to
help you.
Unplug sensor A
If the display is not powered on and showing either two minus signs
“– –“ in RED on the display then, check your wiring with the reverse
light again. If the display is neither beeping nor showing the
distance when you went closer to sensor A then plug sensor A for
testing in the slot of one of the other three sensors.
 Unplug sensor A and try connecting sensor B
If everything is working continue with the other sensors.
 ONLY plug in sensor B cable into the Control Box slot B.
Stand 2m away from the sensor B and move slowly towards it. The
display should show the corresponding distance as you move
closer and closer to it.

 Repeat this process for all remaining sensors, one at a
time. Once you are satisfied that everything is working, plug all
sensors to their corresponding slot in the Control Box. Do a final
check to ensure that everything is correctly plug into its right
position.
 Shift the gear back to “Parking” for automatic vehicles
and remove the vehicle’s key. Car holders with gearshift just
remove the vehicle’s key.
Finish the installation
Fix the Control Box to its final position. Ideally it should be in a
dry, clean and protected area. We suggest to place and fix steadily
the Control Box in the trunk of your vehicle, depending on the side
you connected the power cable with the reverse light.
 Fix the Display to its final desired position. We suggest
mounting it with the 3M sticker to the car’s dashboard. Find a good
position for you to read the display clearly. Hide all cables and
wiring for a clean installation.
SPECIAL NOTE
Check the conditions behind your car before (!) reversing.
In some special cases, the display may not be the same as the
real condition due to the sensor position, obstacle shape, reflection
condition and so on.
Here some examples:
In case of small angle of incidence to the obstacle, such as Glass or
other smooth plane, the obstacle may not be detected as the
signals are reflected away.

B will be detected sooner or later, but A may not be detected at all.
Spherical objects have a small and uneven surface area, due to the
curvature of spherical object the signal reflected away, maybe.
Cliff or Water edges where there are no objects directly behind, will
not be detected. Take extra caution in such situation. [Take care of
warning signs as shown as example.]

Foam or sponge-like objects will absorb the signals and detection
may become difficult.
Obstacle A is of low high. Therefore during reversing, obstacle A
will be detected initially, until obstacle A enters the sensor blind
zone. Once obstacle A is in the blind zone, obstacle B will be
detected. So you must be aware although obstacle A is no longer
detected, it is still there!
